JOHN LALLY, OF GREAT NECK, NEW YORK.

BUILDING COLUMN.

Application filed February 23, 1924. Serial 110 694 617.

To all whom it may concern:

Be it known that 1, JOHN LALLY, a citizen of the United States, residing at Great Neck, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Building Columns, of which the following is a specification.

My invention relates to an improvement on the building column cap. shown and described in my U. S. Letters Patent No. 1,47 1.,- 608. dated October 30, 1923, and it is my ob ject to provide a connection between the cap and column body which will not rely solely on welding to hold the parts together and which will give greater strength than is ill obtainable from the use of the invention of said patent. In some municipalities the building codes prohibit the use of building material in which welding is solely relied upon to hold the parts together and it is to meet this condition that the column of this application was produced.

In the accompanying drawing Fig. 1 is a top view of a column embodying my invention; and Fig. 2 a side view, partly in section, of the structure of Fig. 1, on the line 2-2 thereof.

The column comprises a metal shell or tube 1, preferably filled with concrete 2. The cap, or crown plate, 3 has a plurality of flanges l, 5, 6 and 7 cut, punchedor slitted out and bent downwardly as shown in Fig. 2. The pipe 1 is perforated or punched out at 8, 9, 10 and 11 and the free ends of the flanges are forced into the perforations as best shown inFig. 2. Welding may be employed to further unite the free ends of the flanges andthe pipe. A plurality of bolt holes 12, 12, may be punched or drilled in the top plate to tie the beams to the cap by means of bolts.

By this construction the flanges act as brackets or struts for the top plate and any downward thrust on the plate is met in part by the thrust of the ends of the flanges against the walls of the apertures in the body of the casing. By this construction the capis interlocked with the casing without the useof welding and where welding is employed it is not the sole means of uniting the 1 p arts.

l claim 1. A column comprising a metal tube pertorated ad acent its end, a column cap thereon comprising a metal plate with a plurality of flanges slit and punched from said plate at a distance from the edges thereof and bent at an angle to the plane thereof, the free ends of said flanges engaging the perforations in the tube.

2. A column comprising a metal tube perforated ad acent its end, a column cap thereon comprismg a metal plate with a plurality of flanges slit and punched from said plate at a distance from the edges thereof and bent-at an angle to the plane thereof, the free ends of said flanges entering the perforations in the tube and welded thereto.

tions in the tube.

1. A column comprising a metal tube perforated adjacent its end, a column cap thereon comprising a metal plate with a plurality of bolt holes therein and a plurality of flanges slit and punched from said plate at a distance from the edges thereof,

the free ends of said flanges engaging the perforations in the tube.

' In testimony whereof I have affixed -m signature.

JOHN LALLY.
